Ethylene oxide crane tube
Ethylene oxide crane tube

One. Overview

The AL1544 type is a top crane tube specially used for loading and unloading ethylene oxide. The ethylene oxide crane tube has been on the market for many years. After long-term market running-in and quality inspection, it has gradually matured. Crane pipe joints have two types of flange connection, claw type joint box. The connection direction is vertical and horizontal. Emergency pull-off valve can be installed to ensure the safety of loading. This product uses a rotary joint to connect with rigid pipelines and elbows to realize a mobile device that transports liquid media between the car tanker and the storage and transportation pipeline on the trestle. , Flexibility and long life.

Two. Product performance

The key parts of the ethylene oxide crane pipe produced by our company are made of alloy steel and stainless steel, processed by precision CNC machine tools, built-in double-roller support structure, flexible and reliable rotation. The sealing ring has a unique structure and uses PTFE-reinforced PTFE material, which has excellent wear resistance. The sealing surface is polished to provide superior and reliable sealing performance. For crane pipes for loading and unloading highly corrosive media, based on the original pipeline, special structural seals and PTFE-lined steel pipes can be used for loading and unloading acid, alkali and other highly corrosive chemical media. The carbon steel pipe of the main pipeline for conveying medium adopts GB8163-87 standard, while the stainless steel pipe adopts GB / T14976-94 standard. Reasonable spring cylinder balance system makes the alignment operation light and convenient. All pressure-bearing main pipelines are welded by argon arc welding, and after strict flaw detection inspection and hydraulic pressure test, they fully meet the HG / T 21608-96 standard. The whole arm is light and easy to operate with low resistance. All crane tubes used for loading and unloading flammable and explosive media are equipped with high-quality, reasonably designed electrostatic grounding systems, electrostatic resistance is less than 2Ω, and reliable safety performance. The structure is reasonable, with the smallest possible arm size to achieve the largest possible envelope range. The use of high-quality paint, strict and reasonable paint technology, and strict control of each process of painting, ensure the high quality of the surface paint, can well achieve the requirements of anti-corrosion.

three. Use and maintenance

1. When pulling the crane tube, apply the force evenly to avoid collision.

2. After the operation is completed, the crane tube must be pushed to the side of the oil platform, and the crane tube lifting arm 60 ° position, so that the balancer is in a relaxed state.

3. The user should establish a sound maintenance system, check the work of the crane pipe frequently, and do a good job of maintenance.

4. Regularly apply lubricating oil to the rotating part of each pin and spring balancer.

5. If medium leakage is found after using it for a long time, the leaky rotary device should be disassembled, cleaned and maintained, and seals should be replaced.
